Lynch was aided by a friend, 21-year-old sophomore Troy Kiphuth, who waited outside Cain's office while Lynch climbed through the vents. Once inside the office, Lynch unlocked the door and let Kiphuth in. But they were soon caught by Cain who called the police.
The pair was arrested on charges of burglary, according to the Herald Leader.
The attempted heist apparently wasn't Lynch's first time stealing a test from Cain's office. He told police that he'd successfully pilfered an exam earlier in the semester, according to Lexington's WKYT.
"These are very serious charges in a very serious manner and I can assure you a very extensive investigation will be conducted," a university spokesperson told reporters.
